|---|---|---|---|
| 6416-ZZ | GENERIC-ISO | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 80×200×48 mm envelope per ISO 15; seal variant differs (OPEN vs ZZ) — confirm sealing suits the duty. |

How the 6416 model number is decoded
In the 6400-series (ISO 15 diameter series 4) the last two digits encode the bore: 6416 carries bore code 16 = 80 mm. Outside diameter 200 mm and width 48 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 80 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- Mount this 80 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 64xx heavy section at 80 mm bore (200 mm OD) is built for high-load, lower-speed duty; specifying it in a high-rpm motor gives excess heat and short grease life — use 62/63 there.
- The open 6416 has no lubricant retention: grease escapes and contaminants migrate straight into the 80×200×48 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6400-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6416 units.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- The open 6416 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6416-2Z (shields) and 6416-2RSH (contact seals), not suffix-free 6416.
- The 163/125 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6416 bearing?
A 6416 deep-groove ball bearing has a 80 mm bore, 200 mm outer diameter and 48 mm width (3.15 × 7.874 × 1.89 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 6416 bore code work?
The last two digits of 6416 are bore code 16, giving 16 × 5 = 80 mm bore. The 200 mm outside diameter and 48 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6416 mean?
A bare 6416 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 6400 compare with other series at the same 80 mm bore?
The '4' is the heavy diameter series: 200×48 mm, 60.0 mm radial section at 80 mm bore — the highest-capacity single-row 6xx option here, aimed at lower-speed, high-load shafts.
What is the SKF designation and catalogue data for 6416?
In the SKF Rolling Bearings catalogue this size is listed as 6416 — the open (unsealed) execution, 80×200×48 mm per ISO 15. Quoted values: C 163 kN, C0 125 kN, Pu 4.5 kN, limiting speed 4800 r/min, mass 6850 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6416.
